This application claims benefit of U.S. Provisional Application No. 60/801,066, filed May 18, 2006, the contents of which are incorporated herein by reference. This application also claims benefit of priority under 35 U.S.C. § 119 to French Patent Application No. FR 06/03279, filed Apr. 13, 2006, the contents of which are also incorporated herein by reference.

Disclosed herein is a process for improving the coloration of artificially dyed keratin fibers, for example, human keratin fibers, such as human hair, comprising applying a cosmetic composition comprising at least one polymerizable cyanoacrylate monomer and at least one additional agent chosen from conditioning agents and additional compounds.

Also disclosed herein are pretreatment and/or post-treatment processes for the dyeing of keratin fibers comprising applying a composition of the present disclosure to the keratin fibers.

Further disclosed herein are dyeing processes for keratin fibers comprising applying a composition of the present disclosure to the keratin fibers.

It is known practice to dye keratin fibers, for example, human keratin fibers such as the hair, with dye compositions comprising oxidation dye precursors, which are generally known as oxidation bases. These oxidation bases are colorless or weakly colored compounds, which, when combined with oxidizing products, give rise to colored compounds via a process of oxidative condensation. It is also known that the shades obtained with these oxidation bases can be varied by combining them with couplers or coloration modifiers. The variety of molecules used as oxidation bases and couplers allows a wide range of colors to be obtained.

It is also known practice to dye keratin fibers by direct dyeing. The process conventionally used in direct dyeing comprises applying to the keratin fibers direct dyes, which are colored and coloring molecules that have affinity for the fibers, leaving them to act, and then rinsing the fibers.

The colorations resulting therefrom are particularly chromatic colorations, but are, however, temporary or semi-permanent since the nature of the interactions that bind the direct dyes to the keratin fiber and their desorption from the surface and/or core of the fiber are responsible for their weak dyeing power and their poor wash-fastness.

The artificial color of hair provided by a direct or oxidation dyeing treatment is generally satisfactory on the day of application. However, these colors gradually diminish as a result of repeated washing, and the tints fade to produce colors that are less vivid and less aesthetic. This is particularly noticeable for “warm” shades containing red or coppery hues.

The use of commercial rinse-out and leave-in care products has hitherto not sufficiently improved the color-fastness of the artificial color of hair.

It is thus desirable to develop methods for protecting the artificial color from the effect of repeated washing and the effect of time.

Moreover, depending on the treatments to which the hair has been subjected (e.g, permanent-waving, successive bleaching, and/or dyeing), its condition may be relatively heterogeneous on the same head of hair. When a coloration is applied to this hair, commonly known as sensitized hair, the overall color obtained is not always uniform. It is thus desirable to provide treatments that, when applied before dyeing, make it possible to obtain a more uniform overall dyeing result, also known as unison.

Accordingly, there is a need for compositions that can lessen the inherent effect of the quality of the keratin fiber to be dyed on the expected hair coloration.

It is known practice, for instance, as described in French Patent Application No. 2 833 489 to use hair treatment compositions comprising electrophilic monomers, which can produce a coating on the hair that can remain after shampooing.

The present inventors have discovered, surprisingly and unexpectedly, that it is possible to use at least one electrophilic monomer in the presence of at least one conditioning agent and/or at least one additional compound for the purpose of solving at least one of the problems mentioned above.

The present inventors have also discovered, surprisingly and unexpectedly, that by applying a composition as disclosed herein to the hair, remanent coating or sheathing is formed in situ. Without wishing to be bound by theory, it appears that the hydroxide ions (OH⁻) contained in water at neutral pH are absorbed by the hair and trigger the anionic polymerization process at the composition-hair interface. The at least one conditioning agent and/or the at least one additional compound present in this composition are thus incorporated into the polymer structure obtained following the in situ polymerization of the cyanoacrylate monomer. The production of a particular coating covering the artificially dyed keratin fiber may have a “barrier effect”, thus avoiding the loss of the dyes during successive shampooing, and thus preserving the color of the fiber.

Furthermore, the present inventors have discovered, surprisingly and unexpectedly, that in addition to the effects obtained on the quality and remanence of the hair colorations, the cosmetic properties, such as pleasant feel, softness and/or ease of disentangling, can also be conserved during successive washing. Similarly, the production of a particular coating covering a sensitized keratin fiber may make it possible to unify the surface state of the hair before dyeing, without, however, opposing the uptake of the dyes, and may do so in a long-lasting manner.

The present inventors have also discovered, surprisingly and unexpectedly, that the application of a cosmetic composition of the present disclosure before or after hair dyeing can make it possible to obtain highly cosmetic deposits on the hair, the hairs not being stuck together and the deposit being smooth and being able to remain after shampooing.

Depending on the chosen formulation, this deposit may be accompanied by a gain in mass and in styling properties for the entire head of hair, or, in contrast, may have a non-“visible” natural feel.

As used herein, the term “human keratin fibers” means head hair and body hair, for example, the beard, moustache, eyelashes, and eyebrows.

As used herein, the term “artificially dyed keratin fibers” means keratin fibers dyed via a direct dyeing process and/or via an oxidation dyeing process.

As used herein, the term “washing” means at least one application to keratin fibers of a rinse-out aqueous composition, which is usually detergent, such as a shampoo. This expression also includes bathing and swimming, for example, in the sea and in a swimming pool.

As used herein, the term “conditioning agent” means any agent whose function is to improve the cosmetic properties of the hair, for example, the softness, disentangling, feel, smoothness, and/or static electricity.

Disclosed herein is thus a process for improving the color of artificially dyed keratin fibers, for example, human keratin fibers such as human hair, comprising applying a cosmetic composition comprising at least one polymerizable cyanoacrylate monomer and at least one conditioning agent and/or at least one additional compound chosen from fillers, mineral bases, organic bases, and C₁-C₈ lower alcohols.

Also disclosed herein is a process for protecting the color of artificially dyed keratin fibers and their cosmetic properties with respect to washing.

Further disclosed herein is a process for treating keratin fibers to unify the color of the fibers following the dyeing thereof.

Still further disclosed herein is a dyeing process comprising applying to human keratin fibers, for example, the hair, a dye composition (A), and a composition (B) comprising a cosmetic composition of the present disclosure, wherein composition (B) is applied to the fibers before and/or after the application of composition (A).

Also disclosed herein is a multi-compartment coloring kit comprising at least one first compartment comprising a dye composition and at least one second compartment comprising a composition of the present disclosure.

Processes

Disclosed herein is a process for treating keratin fibers, for instance, human keratin fibers such as the hair, wherein a composition of the present disclosure is applied to the fibers in the presence of at least one nucleophilic agent.

According to one embodiment, the at least one nucleophilic agent capable of initiating the polymerization of the at least one cyanoacrylate monomer may be applied to the keratin fibers before application of the cosmetic composition of the present disclosure. The at least one nucleophilic agent may be used pure, as a solution, in the form of an emulsion, or it may be encapsulated. It may also be added to the anhydrous composition at the time of use just before application to the keratin fibers.

In one embodiment, the at least one nucleophilic agent is water. This water may be provided, for example, by premoistening the keratin fibers. In another embodiment, water may also be added directly to the composition before application.

According to a further embodiment, it is possible to modify the polymerization kinetics by premoistening the fiber with an aqueous solution whose pH has been adjusted using an agent chosen from bases, acids, and acid/base mixtures. The acid and/or the base may be mineral or organic.

It is also possible to perform multiple applications of the composition of the present disclosure in order to obtain a superposition of coats to achieve specific properties for the deposit in terms of chemical nature, mechanical strength, thickness, appearance, and/or feel.

In order to improve, inter alia, the adhesion of the poly(cyanoacrylate) formed in situ, the fiber may be pretreated with any type of polymer.

To modify the anionic polymerization kinetics, the nucleophilicity of the fiber may also be increased by chemical transformation of the keratin fibers. For example, the disulfide bridges, of which keratin is partly composed, may be reduced to thiols before applying the composition of the present disclosure. Examples of reducing agents for the disulfide bridges of which keratin is partly composed, include, but are not limited to: anhydrous sodium thiosulfate, powdered sodium metabisulfite, thiourea, ammonium sulfite, thioglycolic acid, thiolactic acid, ammonium thiolactate, glyceryl monothioglycolate, ammonium thioglycolate, thioglycerol, 2,5-dihydroxybenzoic acid, diammonium dithioglycolate, strontium thioglycolate, calcium thioglycolate, zinc formosulfoxylate, isooctyl thioglycolate, DL-cysteine, and monoethanolamine thioglycolate.

Also disclosed herein is a process for improving the color of artificially dyed keratin fibers, wherein at least one cosmetic composition of the present disclosure is applied before and/or after dyeing the said fibers, in the presence of at least one nucleophilic agent as defined above; wherein the at least one nucleophilic agent is present in the cosmetic composition or contained separately.

According to one embodiment, when the composition according to the present disclosure is applied to the fibers after dyeing the hair, the process can make it possible to protect the color from successive washes and to improve the cosmetic properties following these washes.

This process may be performed in a single stage or in two stages. When the process for protecting the color is performed in two stages, the first stage comprises applying a composition containing at least one nucleophilic agent to the fibers after the fibers have been dyed and wrung dry. The fibers may then be optionally dried. The second stage comprises applying a cosmetic composition as defined above and not containing a nucleophilic agent to the fibers.

It one embodiment, prior to applying the composition containing at least one nucleophilic agent, a composition containing at least one cosmetic additive may be applied to the fibers.

In another embodiment, the fibers may be rinsed and/or washed with shampoo before the application of the composition containing at least one polymerizable cyanoacrylate monomer and at least one conditioning agent and/or at least one additional compound as defined herein.

In yet another embodiment, the process may further comprise totally or partially drying the keratin fibers with a hairdryer and optionally a final shampooing.

According to a further embodiment, the process for protecting the color of the keratin fibers may comprise a step of heating the cosmetic composition to a desired temperature, and then applying the heated composition directly to the keratin fibers. The temperature may range, for example, from 60 to 120° C.

According to another embodiment, the process for treating the color of the keratin fibers may comprise a step of heating the keratin fibers after application of the cosmetic composition.

The heating of the keratin fibers may be performed, for example, using an iron, a liquid water/steam mixture, and/or by using a heating hood.

The heating iron can be chosen from those conventionally used in the field of haircare, for example, crimping irons and smoothing irons. Other examples of irons that are useful in accordance with the present disclosure include flat or round irons described in U.S. Pat. Nos. 4,103,145, 4,308,878, 5,983,903, 5,957,140, and 5,494,058. The iron may be applied by successive separate touches of a few seconds, or by gradually moving or sliding it along the locks. In at least one embodiment, there may be a pause between the application of the color-protecting composition and the application of the heating iron to the keratin fibers. Such a pause can range, for example, from 30 seconds to 60 minutes, such as from 1 to 30 minutes.

The liquid water/steam mixture which may be used in accordance with the present disclosure may have a temperature of at least 35° C.

The liquid water/steam mixture may constitute a mist and may also comprise at least one other gas such as oxygen and nitrogen, mixtures of gases such as air, and other vaporizable compounds.

In at least one embodiment, the temperature of the liquid water/steam mixture may be greater than or equal to 40° C., for example, it may range from 40° C. to 75° C.

In another embodiment, the liquid water/steam mixture can be placed in contact with the fiber for a time ranging from 1 second to 1 hour, for instance, from 5 minutes to 15 minutes. The application of the mixture may be repeated several times on the same fiber, each operation being performed for a time as indicated above. In at least one embodiment, the cosmetic composition is first applied to the hair and these locks thus impregnated are then subjected to the action of the liquid water/steam mixture under the conditions mentioned above, and the locks thus treated are then cooled, for example by sending over or through them a stream of cold or via ambient temperature air.

The liquid water/steam mixture used in accordance with the present disclosure may be produced using any apparatus known in the art and intended for this purpose. According to the present disclosure, the liquid water/steam mixture is diffused onto the keratin fibers using an apparatus comprising at least one steam generator directly connected to a hood. A non-limiting example of this type of apparatus is that sold under the name Micromist® by the company Takara Belmont.

The processes mentioned above may be performed on the actual day of dyeing or at least one day (for instance, from 1 to 60 days) after dyeing.

Also disclosed herein is also a process for treating keratin fibers to unify the color of the fibers after dyeing them. This process comprises washing the fibers, wringing the fibers dry, dyeing the fibers, and then applying to the fibers a cosmetic composition of the present disclosure comprising at least one nucleophilic agent.

According to one embodiment, the process for treating the keratin fibers to unify the color of the fibers after dyeing them may be performed in two stages. The first stage comprises washing the fibers, wringing the fibers dry, dyeing the fibers, applying to the fibers a composition comprising at least one nucleophilic agent, and optionally drying the fibers. The second stage comprises applying to the fibers a cosmetic composition of the present disclosure which does not comprise any nucleophilic agent.

According to at least one embodiment, a composition containing at least one cosmetic additive may be applied to the fibers prior to the application of the composition containing at least one nucleophilic agent.

Two identical locks were prepared for each type of dyeing.

One lock was shampooed and the other was treated with the compositions of the present disclosure and then received the same number of shampoo washes.

The color of the locks was subjected to examination by a panel of experts. Colorimetric measurements were also taken, which confirmed the visual evaluations.

Example 1 Dyeing with Coppery-Red Maji Contrast

The following composition was prepared: α,ω-Dihydroxylated polydimethylsiloxane/cyclo- 45 g pentadimethylsiloxane (14.7/85.3) sold by Dow Corning under the name DC 1501 Fluid Cyclopentadimethylsiloxane sold by Dow Corning under the 44.75 g name DC245 Fluid Acetic acid 0.25 g Methylheptyl cyanoacrylate from Chemence 10 g

0.25 g of this composition was applied by brush to a lock of 1 g of grey hair dyed beforehand with coppery-red Maji Contrast. The lock was dried under a hood for 30 minutes and then combed. At this stage, the lock may be subjected to a final shampooing. The hair felt soft and tangle-free.

After shampooing 15 times, the color of the lock dyed and then treated according to the present disclosure was markedly more vivid than that of the lock dyed identically with coppery-red Maji Contrast and shampooed 15 times according to the same procedure.

Example 2 Dyeing with Coppery-Red Maji Contrast

The following composition was prepared: Olive oil 90 g Methylheptyl cyanoacrylate from Chemence 10 g

0.25 g of this composition was applied by brush to a lock of 1 g of grey hair dyed beforehand with coppery-red Maji Contrast. The lock was dried under a hood for 30 minutes and then combed. At this stage, the lock may be subjected to a final shampooing. The hair felt soft and tangle-free.

After shampooing 15 times, the color of the lock dyed and then treated according to the present disclosure was markedly more vivid than that of the lock dyed identically with coppery-red Maji Contrast and shampooed 15 times according to the same procedure.

Example 3 Dyeing with Coppery-Red Maji Contrast

Lotion A containing 0.6% of monoethanolamine in water was prepared.

Composition B below was prepared: α,ω-Dihydroxylated polydimethylsiloxane/cyclo- 45 g pentadimethylsiloxane (14.7/85.3) sold by Dow Corning under the name DC 1501 Fluid Cyclopentadimethylsiloxane sold by Dow Corning under the 45 g name DC245 Fluid Methylheptyl cyanoacrylate from Chemence 10 g

Three locks of 1 g of grey hair, M1, M2, and M3, were dyed with a Maji Contrast coppery-red dye.

0.25 g of lotion A was applied to lock M1. 0.25 g of composition B was then applied by brush. The lock was dried under a hood for 30 minutes and then combed. At this stage, the lock may be subjected to a final shampooing.

In parallel, 0.25 g of composition B was applied by brush to lock M2. The lock was dried under a hood for 30 minutes and then combed. At this stage, the lock may be subjected to a final shampooing.

Lock M1 was shinier than lock M2.

After shampooing 15 times, the color of the two locks dyed and then treated according to the invention, M1 and M2, was markedly more vivid than that of lock M3 dyed identically with coppery-red Maji Contrast and shampooed 15 times according to the same procedure.

The combination of lotion A and of composition B made it possible to improve the appearance of the locks while at the same time maintaining a color-protecting effect of the same level as that obtained with composition B alone.
